Degassing & Organiser

 

SYKAM S 7505/7510 Vacuum Degasser

The degassing of solvents is very important in liquid chromatography, as oxygen and other in the solvent dissolved gases affect the analysis for various reasons; through the volume contraction (gradient mixing), different pressure ratio (in front and behind the column) and caused by different temperatures, the dissolved gases are released in course of time. This will influence the reliability of the analysis (pump) as well as the detection efficiency (measuring cell). Therefore, dissolved gases have to be removed from the solvent.

Operation Principle of the Degasser In a vacuum chamber, the solvent to bedegassed is distributed into several, parallel arranged, semi-permeable membrane chambers. When a high vacuum (more than -850 mbar) is applied, only the in the liquid dissolved gases are diffusing through the thin membrane. With a total solvent volume of 8 ml per degassing channel, the Sykam Degasser S 7510 achieves an extremely low remaining gas concentration of 0.5 to 5 ppm oxygen, depending on the degasser‘s flow rate (0 to 10 ml/min). With a given flow rate, the degassing quality can be further increased by coupling two or several membrane channels.degassing

The digital display of the actual vacuum in Milibar makes the Sykam Degasser S 7510 the first vacuumt. degasser on the market which functions can be checked and documented at any time.  On top of that, the actual vacuum run can be continuously registered via an analogue DC output (-1 V for 1000 mbar). Through in integrated logic, any leakage in the vacuum system is detected (run time of the vacuum pump for defined vacuum range) and is not only optically displayed by a controll LED but is also indicated through a relay contact closure for peripheral systems. For removing possibly existing solvent traces, the vacuum pump‘s waste gases can be directed via a fixable tube connection to the laboratory‘s ventilation. The Teflon membrane packages are exchangable, in case of damage.

SYKAM S 7131 Reagent Organizer

The S 7131 Reagent Organizer is the optimal solution for storing your solvents. The integrated gas supply with pressure regulator let you store the eluent under inert-gas pressure, or for degassing purposes using Helium. The organizer can hold up to four eluent bottles, which can be closed indivdually with the integrated valve bottle caps. The S 7131 Reagent Organizer could be used with the S 2100 Solvent Delivery System.
